2 Tracks 2 Tasks¶

Track {CTA, MRA}¶

Participants can choose from two tracks, one track for CTA modality and one track for MRA modality. We encourage participants to take part in both tracks.

Task {Binary, Multi-Class}¶

The segmentation task is divided into two (sub-)tasks: binary segmentation of CoW vessels, and multi-class CoW vessel anatomical segmentation.

Participants can choose to only tackle the multi-class segmentation sub-task, as the multi-class segmentation can be converted into a binary segmentation evaluation. If participants only submit for the multi-class segmentation, the results will be automatically evaluated for binary segmentation by us as well, thus considered taking part in both sub-tasks.
